New stuff I try to use M6, but I have lots of telco racks and telco stuff is all 12-24 (probably even to this day).
I’m sure there’s some 10-32 and M5 screws around also, but being an old telco industry guy, I consider those too wimpy. I guess I accept the 10-32 stuff as legacy IT rack standard just like 12-24 is legacy telco rack standard. Anything I do metric is new, so M5 just doesn’t make sense. Luckily most new stuff has the square holes so I just need a bag of M6 cage nuts. Now if I could just find my tool for inserting and extracting cage nuts. What I hate is stripping the threads in an old rack because I think it’s one size and it’s another.

I think we settled on 12-24 for the majority of the equipment we have.

The IEC standard prefers M6x1, and the IEA/ECA standard prefers M5. I'm assuming that you're talking about either a M5 or a M6 screw, not a non-metric 10-32 or 12-24.

If you get rid of the handles please leave a tapped hole in the center of the 1U bracket that matches the common rack screw (there are two standards - pick one) to use as a jack screw if the unit is being stubborn coming out of the rack.

Not really a big deal unless it’s a super long, heavy server, and those typically go in 4 post racks or cabinets anyway with rear access.

I'm in the process of switching the enclosure manufacturer on the RackInjector and in the process making some design changes that should make things better for both us and our customers. I don't want to share too much just in case this doesn't work out - and no, this isn't a change to hot-swappable cards. With the design we're working on, the handles we have on the front of the existing enclosure aren't very easy to implement in the new design. So I'm thinking about just dropping them to save the hassle/pain/shipping issues/cost/etc/etc/etc. My personal experience has been that although handles on enclosures are nice when removing a device from a rack, they are by no means necessary. On occasion, I've also had handles become a liability instead of a help. But on the other hand, when a device gets stuck in a rack (typically due to neighboring devices), it is nice to have them to add leverage when removing the enclosure. I'm wondering what everyone else's thoughts on this are... -- - Forrest -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- <http://remotelylocated.com/wp-content/uploads/2012/07/cropped-Remotely-Located-Logo.jpg> Jason Wilson Remotely Located Providing High Speed Internet to out of the way places. 530-651-1736 530-748-9608 Cell www.remotelylocated.com <http://www.remotelylocated.com/> -- AF mailing list <mailto:AF@af.afmug.com> AF@af.afmug.com <http://af.afmug.com/mailman/listinfo/af_af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- - Forrest -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
